Add log diagnostic context
As it's not trivial to use MDC directly from logging framework in reactive application, we need to do some work manually. The approach proposed is an explicit MDC handling, which means that context is kept as an object created after establishing client connection. Next, new instance of HvVesCollector (and its dependencies) is created. Every object is propagated with ClientContext so it can use it when calling logger methods. In the future ClientContext might be used to support other use-cases, ie. per-topic access control. As a by-product I had to refactor our Logger wrapper, too. It already had too many functions and after adding MDC number would be doubled.
